Have you ever wanted to know the secrets behind all the cool things that WordPress plugins and themes can do? This course is offered by an instructor who has developed over 250 WordPress plugins for major corporations and can now teach these skills to you.
For Those Developers Who Would Like To Know How To Develop Powerful WordPress Plugins!
After getting frustrated, because maybe a downloaded plugin does not fit your needs, why not take your WordPress programming skills to the next level and really learn how to develop your own plugins or customize other downloaded plugins to fit your needs?
For PHP Developers
Programming in WordPress is a snap when you already know PHP. This course shows how to take that PHP experience and parlay into professional WordPress development.
GET OVER 14 FREE PLUGINS INCLUDED WITH THIS COURSE AND LEARN HOW TO DEVELOP THEM ALL FROM SCRATCH OR CUSTOMIZE THEM AS NECESSARY AFTER I TEACH YOU THEIR CODE!
Some Videos Come With FREE Complete Plugins
Besides just teaching the advanced concepts, some videos come with complete plugins that can be downloaded and used immediately after some customization as explained in each video.
In this course, I teach the powerful WordPress development concepts from:
When students finish this course, they will have a powerful WordPress programming skill that most developers do not have and trust me, this looks amazing to other programmers and on your resume.
Some programmers ask me why we program plugins for WordPress, so in this video, I explain the details of plugins.
Learn the lines of code that make up plugins. I take you through the complete architecture of a plugin and show you how to construct your own.
Two of the most common questions I get are:
I explain in this video the major differences, but believe it or not, they are not really that different.
Check this list out often as I constantly show you how to work with WordPress hooks, which are the most important tool in any WP developer's arsenal for creating powerful and professional themes and plugins. Without hooks, WordPress could not be able to allow developers to extend it.
Scenario: What if you or your client's website needs to correct the spelling of your company name? Every time they type a company name, they forget to capitalize the name of the company. For branding purposes, it is important to capitalize the name of the company.
In this video tutorial, we show how to fix any capitalization issues with filter hook called the_filter. This hook allows us to modify any content.
For this example, we show how to fix the common error of spelling "WordPress" with a lowercase "p".
We can create post programmatically when someone submits post data through a form or through another resource such as an RSS feed. In this video, I will show the wp_insert_post() function.
User profiles can contain more than just the normal thumbnail and URL. Watch this video on how to create new and additional user fields.
In this lecture, we learn how to remove menu items from any administrator user. For example, you may not want a specific admin to have access to plugins or the settings menu.
WordPress comes with this really awesome built-in function called bloginfo() that returns all kinds of information, but don't be fooled. This function returns more information that just your regular blog stuff!
Continuing from the previous video lecture, I continue my discussion on bloginfo().
Some plugins and themes contain code to create posts automatically whether from any of these:
If we are going to be powerful programmers, we need to have this skill, so in this video, I demonstrate through a plugin how to create WordPress posts and pages on the fly in the background.
Through powerful WordPress development, we can change the WordPress back end to suit our needs, especially if we are also the administrator.
Watch this video from the instructor on some of the cool things that students will learn in this section.
LET'S CREATE A NEW PLUGIN CALLED THE ADMIN MESSAGE.
What if a WordPress website has multiple writers and contributors. There may be guidelines or rules that each writer has to follow. It makes sense to add those guidelines to the top of any form where posts or pages can be added.
In this video, I show how to add that message with any HTML and CSS to the TOP of any form, so writers will see those messages.
Also, see the attached plugin file that you can modify with your own code in this video.
To start a new plugin file, download the attachment and put it in your wp-content/plugins directory. Rename this file as a .PHP file.
If you have ever logged into the WordPress back end and see those cool dashboard widgets, you may wonder how to create those. This video has the answer and the code.
Sometimes, the default admin message in the footer "Thank you for creating with WordPress." is just not good enough for our website. We can change it with the code in this video.
After you watch this video, please download the code that contains to hook to change the admin footer.
Sometimes, you need a plugin to activate itself. This video teaches students how to do that.
Using the hooks in this video, we will add a message to the END of any form where WordPress posts are added or edited. Any HTML or CSS can be displayed.
Please see the Resources section for this video to download a plugin that you can custom from this video.
Have you wondered how some plugins and themes add links to the left side and where the HTML and PHP are generated after the user clicks those links? That is what I show in this video.
In this tutorial, I explain the following:
The Options API is great for saving options to the WordPress database. They can be set to autoload to save data resources with a simple Boolean variable.
The WordPress API is a way to persist data without the need to create web browser cookies. I present all Transient API functions in this one video.
Once an option is created, it stays in the database until it is deleted. Unlike transients, options do not expire. I show you how to delete an option in less than one minute.
The Options API is not just for single WordPress websites. They also work for WordPress multisites as well. In this video, I explain how to use them in less than 60 seconds.
WordPress' Metadata API is extremely powerful, yet very easy to use and master. In this video, I show how to write one line of code to quickly and safely retrieve information from the three metadata tables in the WordPress MySQL database without writing one line of code.
WordPress' Metadata API also allows developers to change data without writing a single line of MySQL. In this video, I write single lines of code to quickly and safely update the meta data for both users and posts.
Just as easily as we can update meta data, we can also add it from scratch and delete it without writing a single line of MySQL. In this video, I write single lines of code to do just that.
Sample code is attached in the resources section so you can download it and try the following exercises.
Bruce explains why shortcodes are necessary and why it is so important to include in our plugins.
Shortcodes are WordPress' way to provide writers and administrators a way to call WordPress functions without doing the PHP code themselves. They can return simple data or be controlled with attributes that resemble HTML attributes.
In this video, we create a simple shortcode using the Shortcode API to return the date and time to the website visitor without the admin requiring one line of HTML to dynamically call the date and time. All that is needed is a simple PHP echo statement and I show you how to code that in this video.
In the last video, I taught you how to add a simple shortcode that returns the date and time, but what if the writer wants to change the color of the returned output? They need to add an attribute.
In this video, I teach you how to add code to support shortcode attributes.
This plugin comes specifically bare. It only shows the date and time, but in this exercise, students must add support for up to 5 attributes. Read the text in this lecture to see what attributes you should add.
Also, feel free to add your own attributes.
Test your knowledge of the APIs that I taught in this section.
In this introductory video, I explain the benefits of WordPress hooks and their importance for themes and plugins.
The process of writing hooks is easy if we know the basics. In this video, I will explain how to write hooks and their callback functions. You will find them easier than expected.
Hooks come in two flavors. I explain both here and how each type effects WordPress.
Sometimes you have a specific CSS class that you want to include somewhere in the body without the worries of hard-coding them in a theme. If you distribute a plugin with its own CSS classes, you can tell WordPress to add them to the <BODY> tag. I explain how to do that in this video.
Maybe you want to create a theme or plugin that has value for the user. Facebook share buttons are always great for this purpose. I explain how to do it in this video for your theme, but the next video will take the "theme" concept and show you how to do the same thing in your plugins.
This quiz helps students access their knowledge of writing WordPress hooks.
Watch this video to see what every plugin needs and how to make WordPress list it in the Plugins section of every installation.
This is the start of our plugin. We start with the basics by declaring our plugin to WordPress. Then, we add a title, description, version number and author information.
From there, we add our hooks and callback function.
By the end of this video lecture, our plugin will be ready to use.
Please see the resources section of this lecture to download this plugin for free. We will be building it up in subsequent videos in this section.
Some WordPress themes do not always display a post or page's featured image, creating frustration for the administrator. This plugin will always display the featured image regardless of what the theme is doing. It saves time and headaches for the administrator.
The Hello Dolly plugin is probably the most deleted plugin on most WordPress websites, but it serves as a great beginning to plugin development, so in this video, I take you through the code. In the NEXT video, we will spin our own version of Hello Dolly that is personally suited to us.
We can programmatically create thumbnail sizes instead of using the defaults that come with WordPress such as 'thumbnail', 'large', etc. In this video, I show you how to add image sizes including their width, height and cropping options and then how to apply them to a WP_QUERY loop.
We can tell WordPress how to position crops when adding images.
We can include our custom thumbnail size in a hook called "After Theme Setup" which lumps together multiple functions after the theme is loaded into WordPress.
In this video, I demonstrate how to set up this action hook in the functions.php of my theme. This hook makes your theme more efficient.
When adding media to our posts and pages, we can select exactly what custom images to include in the image selector with 6 lines of code activated by a filter hook.
In this video, I show how to code the image_size_names_choose filter hook to make this happen.
There may be a situation when you need to retrieve just the thumbnail URL of a featured image. One use could be to send people a logo or to link to one from any post of page, other than the featured image from a current ppost that displays through WP_QUERY.
In this video, I show you several ways to get that information from obtaining the post ID to getting the ID of the thumbnail (called the attachment in the WordPress world). The URL will be retrieved with these variables.
Test your knowledge on image size development
We have all seen the lyrics to Hello Dolly thanks to this plugin that gets distributed with every WordPress installation, but what if we want to CHANGE those lyrics? We can with this plugin.
In this video, I teach you two action hooks to change the lyrics as well as the admin_head action hook to dynamically add CSS styles that would not come with the admin's theme.
This video explains how to capture users in various criteria and show messages specifically to them. The accompanying plugin for this video contains code for all scenarios.
In the video, I teach you how to detect who the user is and to capture information about them such as username, email, first and last name. We do not get their password for privacy reasons.
Just because an authorized user does not know the administrator login information does not mean that they can still hack the form. Hackers can use brute force techniques to enter with improper security settings.
In this video, we look at code to protect our backend in a private administrator environment where we can redirect unauthorized users and hackers to our home page.
This video also includes a plugin that you can customize in the Resources section.
In this video, I demonstrate how to add code to any plugin or your theme's functions.php file to replace content entered into any post or page using the WordPress filter hook called "the_content" and PHP's ereg_replace to replace dynamic code with regular expressions. We use an example of generating a secure Paypal form with Paypal's hosted button ID.
Additional concepts in this video explains why we need to wrap our WordPress plugins within PHP classes to prevent duplicate naming problems that normally occur with WordPress plugins.
This is a complete video on creating a social media plugin that allows the administrator to enter addresses for Facebook, Twitter, LinkedIn, YouTube and more. The plugin will both create a widget using the Widget API and a template tag that can be added to any theme.
You can create a library of as many shortcodes as you'd like and put them all into one handy plugin. Here, we create a basic library of 2 basic shortcodes and you are free to add as many more as you'd like.
We are taking this a few steps at a time. In this video, I will show you how to get the menu link on the left and how to display the upload form.
This is part 1 of the code where we complete the plugin. In this video, you will learn how to:
Get the finished plugin in the Resources section for this video.
This is part 2 of the code where we complete the plugin. In this video, you will learn how to:
Check out the Resources section of the previous video (part 1) for the entire plugin.
I show you how the tabbed instructions work as well as how to:
Although most WordPress themes come with their own search bars, they search everything from posts, pages, and custom post types, but if you just want a search bar to work for a specific custom post type and not posts or pages. We will develop this plugin to accomplish that. We will develop this plugin as a shortcode that can be added anywhere in a theme or the content editor.
I Have a plugin that you can customize to allow the admin to add ratings with custom background colors and icons. It is based off of a star rating system, but you can substitute any icons you like instead of stars and customize the HTML and CSS anyway you see necessary,
